Diaper Dermatitis

Diaper dermatitis is the most common skin eruption in infants and toddlers. It typically occurs on convex skin surfaces that are in direct contact with the diaper, including the buttocks, lower abdomen, genitalia, and upper thighs. Diaper rash is usually caused by skin being exposed to moisture for too long. The moisture irritates the skin, which starts to break down. The skin gets damaged when it rubs against the diaper. Chemicals in the urine and stool can further hurt the skin and could cause a rash. Irritated skin can be at risk for infection.
